I think it's 9.5, but I've kind of forgotten how to do this stuff too.
The median is the central value, 10.
Median = 15
It is 8.
Mean: 13.6 Median: 15 Mode: 16, 18, 15, 9, 10
The median is 13.5
To work out the median, we firstly rearrange these numbers into numerical order: 3 6 9 10 The middle number is the median. However, in this example, there is no middle number, so we take the mean of 6 and 9 (mean: (6+9)/2=7.5). So the median is 7.5
8.5
First, to find median put numbers in order so: 5, 5, 6, 7, 8, 9, 10, ( 10, 12 ,) 14, 15, 17, 18, 18, 18, 20 10 + 12= 22 divided by 2= 11, the median is 11
The median is the central number when the values are arranged in ascending or descending order. To find the median of the given numbers, they must be arranged:4, 6, 9, 11, 15 (ascending order)15, 11, 9, 6, 4 (descending order)The number that holds the central position is 9, therefore, 9 is the median of the given set of numbers.
8. In order: 4, 6, 7, 9, 10, 12 6 data items so median is mean of middle two: median = (7+9)/2 = 8.
Mean = 13.44.. recurring Median = 15 Mode = 9 and 15 Range = 17
